TB/T 1979 09CuPCrNi-A atmospheric corrosion resistant steel plates are widely used corten steel materials. BBN steel supply 09CuPCrNi-A steel plates to users to make steel structures, such as railways, vehicles, bridges and towers, which are exposed to the atmosphere for a long time.

COR-TEN has served as weathering steel (atmospheric corrosion- resistant steel). Corten steel plate has successfully overcome rust, steel’s most weakest. When exposed to the atmosphere without painting, corten steel begins to rust in the same way as ordinary steel.

05CuPCrNi weather steel advantages and purpose. ... causes the component manufacturing, users benefit. Such as weathering steel bridge can save the coating cost can be as high as 10% of construction investment. 4, steel structure has many unique advantages, such as high strength, high toughness, shock resistance, light weight, low cost, little ...
